Wide text printing .................... ESC ESC t n 1B 1B 74 n 27 27 116 n This sequence enables and disables wide text printing
Enable .................................. ESC ESC t 1 1B 1B 74 31 27 27 116 49 Wide-carriage printers can print up to 16 inches across;
Disable ................................. ESC ESC t 0 1B 1B 74 30 27 27 116 48 narrow-carriage printers can print up to 11 inches across. When
wide text printing is disabled, the leftmost and rightmost print
positions, margins and horizontal tabs return to their original
locations.
With wide text printing enabled, text prints unidirection-ally; that
is, text printing occurs only while the carriage moves from left-
to-right across the platen. Also, the letter- and memo-quality
print speeds are slower than normal.
This sequence does not affect graphics printing. If you want to
print wide graphics, you must use the Wide Graphics sequence.
)Note: With wide text printing enabled, be sure to load paper in
the printer so that it aligns with the blue line on the paper scale.
This ensures that printing does not run off the left side of the
page.

Print Epson JX .......................... ESC * m 1B 2A m 27 42 m This sequence prints bit-image graphics, wherein character
graphics n1 n2 list n1 n2 list n1 n2 list codes no longer print characters, but instead print 8-dot-high
columns of dots on the current print line. Depending on the
mode, the columns are spaced from 1/60 to 1/240 inch apart.
This sequence does not change the current line spacing. Variable
m in the sequence determines which graphics mode the printer
uses:
Variable m
Mode Resolution ASCII Hex Dec
Single 72V x 60H dpi NUL 00 0
Double 72V x 120H dpi SOH 01 1
HS double 72V x 120H dpi STX 02 2
Quadruple 72V x 240H dpi ETX 03 3
Epson QX-10 72V x 80H dpi EOT 04 4
One-to-one 72V x 72H dpi ENQ 05 5
Other CRTs 72V x 90H dpi ACK 06 6
In the HS double and quadruple modes, consecutive hori-xontal
dots are not permitted. If the sequence specifies consecutive
horizontal dots, the printer does not print the second dot.
Variables n1 and n2 define the number of columns to print. This
number equals the number of bytes in the list. The printer
interprets n1 and n2 as follows:
Number of columns = (256 x n2) + n1
